Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, and specifically relates to an auxiliary device for replacing adsorbed material on a 3D printing platform. Background Technology

[0002] Thermoforming is a composite process with 3D printing, or a technique involving the adsorption and forming of thermoplastic materials during 3D printing. Thermoforming involves heating a sheet of thermoplastic to a softened state, adsorbing it onto the surface of a mold through vacuum or pressure, and then cooling it to form the final product. When combined with 3D printing, there are two main application modes: 3D printed mold + thermoforming: using 3D printing technology to create a thermoforming mold, and then using the thermoforming process to produce the final product, enabling small-batch customized production.

[0003] In current thermoforming applications, thermoplastic sheets need to have a certain positioning effect when covering the mold to prevent warping and air leakage, which can lead to poor adsorption and poor forming results. Furthermore, it is not convenient to quickly match and adjust the outer frame of thermoplastic sheets of different sizes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for replacing adsorbed materials on a 3D printing platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a 3D printing platform adsorption material replacement auxiliary device, comprising a crossbar, a base plate fixedly installed on one side of the crossbar, side rods fixedly installed on both sides of the top of the base plate, a contact plate provided on the inner side of the side rod, a screw rod 1 rotatably connected to one side of the contact plate through a bearing and extending through to one side of the side rod, a side block provided on the top of the side rod, and a screw rod 2 rotatably connected to the inside of the crossbar through a bearing, with threaded blocks threaded to the top of the crossbar at both ends of the surface of the screw rod 2.

[0006] Preferably, a placement cavity is formed between the two side rods, and a receiving cavity is opened on one side of the side rod, with the contact plate located inside the receiving cavity.

[0007] Preferably, the side rod has a threaded hole inside for use with a screw rod, the threaded hole and the screw rod are threadedly connected to each other, and a knob located on one side of the side rod is fixedly installed at one end of the screw rod.

[0008] Preferably, both ends of one side of the contact plate are fixedly installed with guide rods that extend to one side of the side rod. The side rod has a guide hole inside that is used to cooperate with the guide rods. The guide hole and the guide rod are slidably connected to each other.

[0009] Preferably, an end block is fixedly installed on one side of the top of the crossbar, and an arc-shaped guide surface is formed on one side of the end block, and an arc-shaped guide surface is formed on one side of the side block.

[0010] Preferably, the threaded block and the edge block are fixedly connected to each other, and the top of the crossbar is provided with a through groove for use with the threaded block.

[0011] Preferably, a bevel gear is fixedly sleeved on the surface of the screw two, a bevel gear two meshes with the surface of the bevel gear one, and a rotating rod that is rotatably connected to the crossbar is fixedly sleeved inside the bevel gear two.

[0012] Preferably, one end of the rotating rod extends through to the rear side of the crossbar and is fixedly mounted with a knob two, and the top of the crossbar is provided with a scale.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. In use, the contact plate is initially positioned in the receiving cavity. The external adsorption platform is placed in the placement cavity, with one end of the external adsorption platform abutting against one side of the crossbar. Then, simultaneously adjusting knob one, the contact plate moves closer to the adsorption platform for contact. This design utilizes the contact plate to fix the adsorption platform in place. This structure overcomes the inconvenience of existing bolt-type fixing and can be used to install and fix adsorption platforms of different sizes to meet various 3D printing needs.

[0015] 2. In the initial use of this utility model, when it is necessary to cover the top of the adsorption platform with the thermoplastic sheet outer frame and the thermoplastic sheet, one end of it abuts against the end block. The thermoplastic sheet outer frame of the same size can be directly inserted between the two side blocks, and the placement is guided by the arc-shaped guide surface. At this time, it can be used to position the adsorption platform and the outer frame, which brings convenience for subsequent long-term use and is easy to match with thermoplastic sheet outer frames of different sizes, and can complete the rapid positioning and installation of the thermoplastic sheet outer frame.

[0016] 3. In use, when the adsorption platform needs to be disassembled, simply rotate knob one in the opposite direction, and the contact plate retracts into the receiving cavity. The adsorption platform can then be directly pulled out, a process that is extremely quick and convenient. It also features an adaptive and compatible design, overcoming the efficiency and precision bottlenecks of traditional bolt fixing. Furthermore, the thermoplastic sheet outer frame enables plug-and-play quick switching, significantly improving the production flexibility and operational convenience of 3D printing equipment. Suitable for flexible manufacturing scenarios involving multiple varieties and small batches, it has significant engineering implications for promoting rapid changeover in 3D printing production lines.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0024] refer to Figures 1-4A 3D printing platform adsorption material replacement auxiliary device includes a crossbar 1, a base plate 101 fixedly installed on one side of the crossbar 1, and side rods 102 fixedly installed on both sides of the top of the base plate 101. A contact plate 2 is provided on the inner side of the side rods 102. A screw 201, penetrating to one side of the side rod 102, is rotatably connected to one side of the contact plate 2 via a bearing. A side block 6 is provided on the top of the side rod 102. A second screw 7 is rotatably connected to the inside of the crossbar 1 via a bearing. Threaded blocks 9, penetrating to the top of the crossbar 1, are threaded to both ends of the surface of the second screw 7. In use, when the adsorption platform needs to be disassembled, the knob 202 is rotated in the opposite direction, and the contact plate 2 retracts into the receiving cavity 104. At this time, the adsorption platform can be directly pulled out. The process is extremely quick and convenient, and it features an adaptive and compatible design, breaking through the bottlenecks of efficiency and precision in traditional bolt fixing. Simultaneously, it uses a thermoplastic sheet outer frame to achieve plug-and-play quick switching, significantly improving the production flexibility and operational convenience of 3D printing equipment. Suitable for flexible manufacturing scenarios with multiple varieties and small batches, it has important engineering significance for promoting rapid changeover of 3D printing production lines.

[0025] A placement cavity 103 is formed between the two side rods 102. A receiving cavity 104 is provided on one side of the side rod 102. The contact plate 2 is located inside the receiving cavity 104. The placement cavity 103 is used to accommodate the adsorption platform. The receiving cavity 104 provides space for the contact plate 2 to be received by the side rod 102, so that the contact plate 2 can be stored inside the side rod 102 to the maximum extent to prevent it from protruding.

[0026] The side rod 102 has a threaded hole 203 inside for use with the screw 201. The threaded hole 203 and the screw 201 are threadedly connected to each other. A knob 202 is fixedly installed on one end of the screw 201 and located on one side of the side rod 102. The rotation of the knob 202 will drive the screw 201 to rotate. The rotation of the screw 201 will be achieved by the threaded connection with the threaded hole 203, thus realizing the progressive movement inside the side rod 102.

[0027] Guide rods 3 are fixedly installed at both ends of one side of the contact plate 2, extending through to one side of the side rod 102. The side rod 102 has a guide hole 4 inside for the guide rod 3 to pass through. The guide hole 4 and the guide rod 3 are slidably connected to each other. During the movement of the contact plate 2, the guide rod 3 and the guide hole 4 are slidably connected to guide the movement of the contact plate 2.

[0028] An end block 5 is fixedly installed on one side of the top of the crossbar 1. An arc-shaped guide surface 501 is formed on one side of the end block 5, and an arc-shaped guide surface 601 is formed on one side of the side block 6. The end block 5, together with the arc-shaped guide surface 501, limits and guides one end of the thermoplastic sheet frame that needs to be covered on the top of the external adsorption platform. The side block 6, together with the arc-shaped guide surface, limits and guides both sides of the thermoplastic sheet frame that needs to be covered on the top of the external adsorption platform.

[0029] The threaded block 9 and the side block 6 are fixedly connected to each other. The top of the crossbar 1 is provided with a through groove 11 for the threaded block 9 to pass through. When the threaded block 9 moves, it will drive the side block 6 to move synchronously. The through groove 11, in conjunction with the threaded block 9, can limit the angle of the threaded block 9 when it extends to the top of the crossbar 1, so as to prevent the threaded block 9 from rotating with the screw 7.

[0030] A bevel gear 8 is fixedly sleeved on the surface of screw 7. A bevel gear 801 meshes with the surface of bevel gear 8. A rotating rod 802, which is rotatably connected to the crossbar 1, is fixedly sleeved inside bevel gear 801. The rotation of the rotating rod 802 will drive bevel gear 801 to rotate, and the rotation of bevel gear 801 will drive bevel gear 8 and screw 7 to rotate synchronously.

[0031] One end of the rotating rod 802 extends through to the rear side of the crossbar 1 and is fixedly installed with a knob 803. The top of the crossbar 1 is marked with a scale 10. The rotation of the knob 803 will drive the rotating rod 802 to rotate synchronously. The scale 10 is used in conjunction with the movement of the threaded block 9 to check the distance.

[0032] Brief description of the usage process: In the initial state of use, the contact plate (2) is located in the receiving cavity (104). The external adsorption platform is placed in the placement cavity (103), and one end of the external adsorption platform abuts against one side of the crossbar (1). Then, the knob (202) is adjusted simultaneously, so that the knob (202) drives the screw (201) to rotate. The rotation of the screw (201) will be realized through the threaded connection with the threaded hole (203), realizing the progressive movement inside the side bar (102), and driving the contact plate (2) to approach the adsorption platform for contact. At the same time, in the initial use, when it is necessary to cover the top of the adsorption platform with the thermoplastic sheet frame and the thermoplastic sheet, one end of it abuts against the end block (5), and the frame is guided by the arc-shaped guide surface (501). The operator then rotates knob two (803), causing knob two (803) to drive screw two (7) to rotate. The reverse thread design at both ends of screw two (7) will allow the two threaded blocks (9) to move closer or further apart. During the movement of the threaded blocks (9), the two side blocks (6) will move closer together and make the side blocks (6) contact the outer frame. This is the initial adjustment process. In subsequent use, a thermoplastic sheet outer frame of the same size can be directly inserted between the two side blocks (6) and guided by the arc-shaped guide surface two (601). At this time, it can be used in conjunction with the adsorption platform for positioning between the outer frame, which brings convenience for subsequent long-term use.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
